Karl Heinz Marbaise commented on MNG-5838:
------------------------------------------
If you take a deeper look into the output you can see things like this:
{noformat}
java.io.IOException: Function not implemented
at sun.nio.ch.FileDispatcherImpl.lock0(Native Method)
at sun.nio.ch.FileDispatcherImpl.lock(FileDispatcherImpl.java:91)
at sun.nio.ch.FileChannelImpl.lock(FileChannelImpl.java:1022)
{noformat}
which means this on very low level in Java Code and here in the Java classes
itself...You might check the OpenJDK JVM documentations if you find something...
> Maven on No-File-Lock Systems
> -----------------------------
>
> Key: MNG-5838
> URL: https://issues.apache.org/jira/browse/MNG-5838
> Project: Maven
> Issue Type: Bug
> Affects Versions: 3.3.3
> Reporter: Dylan Hutchison
>
> I work on a Lustre file system that does not support file locking. Maven
> emits tons of warnings when it cannot lock a file due to IOExceptions. In my
> case this is not a problem because I only run one maven process at a time and
> the .m2 directory inside my home directory is not shared, so there is no need
> to lock files.
> Maven built correctly despite the warnings when using Maven 3.2.3. Then, when
> I upgraded to Maven 3.3.3, Maven failed on most goals, even clean. I'd like
> to at least compile my code with mvn on this system with no file locking,
> even if it can't run project tests.
> I uploaded log files for running with 3.2.3 and 3.3.3 here:
> <https://gist.github.com/a0099ea87e5ac663b2ac>
> Scroll down halfway for the second file.
> Is there an option to disable file locking?
